Perch Lake Habitat Restoration Project

The Minnesota Department of Natural Resources is accepting comments through May 5 on an Environmental Assessment Worksheet for a proposal to restore aquatic and wetland habitat in the St. Louis River estuary.

The estuary is a waterbody designated by the DNR as a resource of Outstanding Biological Significance located within the St. Louis River Area of Concern. The Perch Lake Habitat Restoration Project would address existing habitat impairments by excavating accumulated sediment and organic deposits in Perch Lake to restore deep water habitat, increase dissolved oxygen concentrations and improve overall water quality.

The installation of a 16- by 12-foot culvert between Perch Lake and the St. Louis River would improve hydrologic connectivity and aquatic organism passage, revitalizing the connection between the waterbodies with increased flow volumes, improved access to overwintering habitat for fish and reduced water residence time in Perch Lake.

Documents

The Minnesota DNR has prepared an Environmental Assessment Worksheet (EAW) for the project. Public notice of the availability of these documents for public comment is in the April 5, 2022 EQB Monitor. A 30-day public review and comment period will be open from April 5, 2022 until 4:30 p.m., May 5, 2022.

A paper copy of the EAW is available for public review at:

  • Carlton Public Library, 310 Chestnut Ave, Carlton, MN 55718

Additional copies may be requested by calling 651-259-5723

The EAW was published in the April 5, 2022 EQB Monitor. Mailed comments on the EAW must be submitted no later than 4:30 p.m. Thursday, May 5 to the attention of Sara Mielke, DNR Ecological and Water Resources Division, 500 Lafayette Road, St. Paul, MN 55155-4025.
